Implement useEmulator for Database #3904

samtstern · 2020-10-07T18:24:50Z

Discussion

This PR is part of a group: #3904 #3906 #3909

In order for useEmulator() to work the Repo has to be changed or replaced. In Android this was easier because the database instance lazily creates the Repo (via ensureRepo()) but in JS the Repo creates the database instance.

In this change I move the repo_ and root_ fields to have getters/setters so that we can track their usage and allow useEmulator() to replace the Repo only if no database operations have been performed yet.

Android implementation:
firebase/firebase-android-sdk#1802

This follows Proposal 2 at:
http://go/firebase-emulator-connection-api

Testing

Added new unit tests

Do you have thoughts on this: https://gist.github.com/schmidt-sebastian/b84902bf402a887ee2b3bc6591a51068

This brings this repo a little close in line with Android (or does it - but it seems simpler).

…se-js-sdk into ss-use-emulator-database

samtstern · 2020-10-16T09:44:16Z

Quoting @schmidt-sebastian from chat:

Reserving seems like a good idea, but I am not sure how complex this would be - but I am sure that it will be more complex than your initial commit
Let's go back to that with some minor tweaks:
s/instanceUsed/started
and can you use the same applyEmulatorSettings naming and logic as you did on Android?
so no clone/delete but rather a mutable Repo class

packages/database/src/api/Database.ts

packages/database/src/core/RepoManager.ts

This reverts commit d3e5503.
